Vehicular Image Synthesis Apparatus

1. A vehicular image synthesis apparatus for a vehicle, comprising: a plurality of cameras mounted on the vehicle, the plurality of cameras being configured to respectively capture images of a driver from mutually different positions; and a controller connected with the plurality of cameras, the controller being configured to compare a plurality of images captured by the plurality of cameras to detect a boundary suitable for synthesis, and to synthesize the plurality of images at the boundary to enable the image of the driver to include no hidden portion, wherein the plurality of cameras include a first camera configured to capture a first image and a second camera configured to capture a second image; the controller is further configured to to calculate similarity degrees between (i) row area images obtained by dividing the first image captured by the first camera into a plurality of row areas and (ii) row area images obtained by dividing the second image captured by the second camera into a plurality of row areas, to detect the row area images with the similarity degree exceeding the preset threshold as the boundary; and in response to calculating the similarity degrees between the row area images of the first image and the row area images of the second image upon determining that the similarity degree exceeds a preset threshold for boundary determination, the controller is further configured to stop calculating the similarity degrees and to detect the row area images with the similarity degree exceeding the preset threshold as the boundary.
